STAY-ROLLER FOR SLIDING DOORS.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed October 23, 1913. Serial No. 796,793.

To all whom it may concern:

Be it known that I, F RED H. I-Irnsn, a citizen of the United States, residing at Manson, in the county of Calhoun and State of Iowa, have invented certain new and useful Improvements in Stay-Rollers for Sliding Doors, of which the following is a specification.

This invention relates to stay-rollers for sliding doors such as barn-doors, and has primarily for its object the provision of a novelly constructed stay-roller which may be moved to inoperative and operative positions simultaneously with lateral movement of the barn-door to such positions.

A further object of my invention is to provide improved means for mounting the stay-roller whereby it may be moved oscillatorily to various positions, whereby the stayroller shall be maintained in a normal position yieldingly and shall be movable to an inoperative position against said yielding action. I

In the accompanying drawings: Figure 1 is a side elevation showing my improved stay-roller applied to a sliding door. Fig. 2 is a similar view but with the door swung laterally from its suspension and having moved the roller to an inoperative position. Fig. 3 is a plan view of Fig. 1, the door being shown dotted. Fig. 4 is a face view of Fig. 1. Fig. 5 is an enlarged vertical sectional view as taken on the line 5-5 of Fig. 1. Fig. 6 is a sectional view taken on the line 66 of Fig. 5.

In the drawings I have illustrated only the lower portion of a door 7, the door being slidable lengthwise (as indicated in Fig. 3) to close the passage 8 of which the beam 9 is the base.

A bracket 10 is secured to base 9 and extends laterally therefrom, having a circular disk-head 11 at its outer end, and said head is formed with a centrally disposed square extension 12 the sides of which form vertical and horizontal cam faces. A bolt13 extends through a centrally disposed horizontal aperture in said head, and mounted turnable upon said bolt and head is a casing 14, a nut upon the bolt holding the casing from axial displacement. The casing carries a radially extending pintle 15 upon which is journaled a roller 16. Lugs 17 extending internally from the casing 14: form a means for holding a flat spring 18 parallel with a side of the square extension 12 and with the body portion of the spring in contact with one of said sides or cam faces, so that, as shown clearly in Fig. 6, the casing is held yieldingly by said spring in a normal position with the pintle and roller upright, whereby the roller forms a stay and guide for the lower edge of the door. An arm 19 extends tangentially from the door side of casing 1 1, spanning the space between the base 9 and the casing, and in such a manner that the free end of the arm terminates just below the bottom of the door.

The roller guides the door as is illustrated in Fig. 1, the roller being maintained in such operative position through means of the spring engaged vertical cam face; and when, through whatsoever force, the door is swung laterally upon its suspension (as shown in Fig. 2) the door will swing the roller and casing against the action of spring 18 until the formerly top horizontal cam face is held in a vertical position by said spring, said cam faces and spring causing the casing to move but a quarter turn when once sufficiently actuated. Thus the arm 19 assumes a vertical position in the lateral path of the return movement of the lower edge of the door, so that simultaneously with the return movement of the door the casing and roller will be moved to normal position through action of the door operating upon the said arm.

Thus the stay-roller is moved to an inoperative position and to an operative position through means of the sliding door moving laterally to such positions; and the stay roller is maintained set in either position by a yielding force which must be overcome to displace the roller.

I claim as my invention:

1. In combination with a sliding door capable of lateral swinging movement, means for guiding the lower portion of the door, said means comprising a support, a casing pivotally mounted on a horizontal axis on the support and being shaped to provide an inclosed compartment, a roller mounted on a vertical axis on said casing and being disposed to engage the outside of the lower edge of the door, and a spring located within the inclosure of the casing and being so arranged and connected with the casing and the support as to hold the casing with its parts in the above described position and to permit the casing to move rotatably against the tension of the spring.

' bermay be moved yieldably rotatably" to' ally from said flat face and having an aperture extending through the bracketand said lug on a horizontal axis, a circularly shaped casing having only one side open, the casing having a coaxially disposed aperture, a bolt extending through the bracket and casing apertures whereby the casing is mounted rotatably on the bracket with its open side covered by said fiat face of the bracket and whereby the square lug is located within the inclosure of the casing, a flat spring located within the casing and cooperating between the same and the square lug forholding' the casing yieldingly from rotary movement but permitting it to rotate at quarter-turn move-" ments guided by the faces-of the lug, a

roller mounted on an arm'carried by theflcasmg, and an arm extending outwardly from the casing and being arranged with such re lation to the" said roller that the casingmay be moved rotatably in opposite directions by the lower'portion of a door located intermediate the roller and arm being moved laterally.

3. In a device of the character described, the combination of a bracket, a casing forming an inclosure open at one side only, the casing being pivotally mounted on a'horiz'ontal axis on the bracket with its open side closed by a face of the bracket, a roller mounted on a upstanding arm rigidly car;- ried by the bracket, an arm extending'outwardly from the bracket and in such relation'tothe roller that the arm may be 013- erated to rotate the casing by ,a member adapted to be guided by the roller, andspring meanslocated within the inclosure of thecasing and cooperating between the easingand bracket for holding the casing'yieldingly from pivotal movement by permitting it to rotatein opposite directions against the spring yielding force to predetermined positions; a

4. In a device of the character described, the combination of a bracket having a lug extending laterally from one face thereof and formed with angularly arranged sides, a pivot-member extending laterallyfrom the lug, a member pivotally'mou'nted to turn on said pivot-member and carrying a fiat spring in contact with one of the faces of the lug whereby'the spring-carrying memdifl'erent'positions determined by the annular facesbf'thelug, a roller'mou'nted on the pivoted member on an axis transverse to Oopien of this patentmay be obtained an thepi'vot axis thereof, and anarmextending laterally from the pivoted member and one of said'fiat faces,afiat spring interposed between a fl'at face of thelug-and said abutment faces with it's endse'ngag'ing thelatter and its "center portion the former whereby the spring is'held'in engagement with the lug face and determines the position of'thecasing, and a roller and an arm carried by the casing, extending outwardly therefrom and' being spaced apart whereby the lower end'porti'on of a door may operate between the arm and roller to be guidedby thelatter and when-moved laterally in one direction will move the roller out of operative'p'osition' by rotating the casing against the'tension of the spring and when returned will;

operate the arm to move the roller to operative position, said angularly arranged faces on thehub determining the operative and inoperative positions of thecasing.

6. The combination with a sliding door capable of lateral swinging movement,- of

means forguiding the lower portion of the door comprising'a bracket adaptedto be fixedly mounted below the door, a casing forming'an inclosure having one side open, the casing being pivotally mounted ona horizo'ntal'axis-on the bracket with its open side closed by'the bracket, a roller mounted on thecasing on a vertical axis and being" positioned to guide the lower outer edge of the door, an arm carried by the casing'and extending below andt'oward the inner side of the door, and means within the casing co-r 511;

operating between the bracket and casing for holding the'casing with its roller inop' erative' relation with the door, for permitting the-casing to rotate by swinging of'the' roller outwardly through swinging ofthe door laterally, and for holding the casing with its said arm extending upwardly inthe path of the door return; 1
